Good Decision Criteria
• “When evaluating capital budgetingdecision rules”, we need to ask ourselvesthe following questions• Does the decision rule
• Adjust for the time value of money?• Adjust for risk?• Provide information on whether we are
creating value for the firm?
9-4
Example 9.1: Project Information
• You are looking at a new project and youhave estimated the following cash flows:• Year 0: CF = -165,000• Year 1: CF = 63,120; NI = 13,620• Year 2: CF = 70,800; NI = 3,300• Year 3: CF = 91,080; NI = 29,100• Average Book Value = 72,000
• Your required return for assets of this riskis 12%.
9-5
Payback Period
• How long does it take to get the initialcost back in a nominal sense?
• Computation• Estimate the cash flows• Subtract the future cash flows from the
initial cost until the initial investmenthas been recovered
• Decision Rule – Accept if the paybackperiod is less than some preset limit
9-6
Computing Payback For TheProject
9-7
Decision Criteria Test - Payback
• Does the payback rule account for the timevalue of money?
• Does the payback rule account for the riskof the cash flows?
• Does the payback rule provide anindication about the increase in value?
• Should we consider the payback rule forour primary decision rule?
9-8
Advantages and Disadvantagesof Payback
• Advantages• Easy to understand• Adjusts for uncertainty
of later cash flows
• Disadvantages• Ignores the time value of
money• Requires an arbitrary
cutoff point• Ignores cash flows
beyond the cutoff date• Biased against long-
term projects, such asresearch anddevelopment, and newprojects
9-9
Discounted Payback Period
• Compute the present value of each cashflow and then determine how long it takesto payback on a discounted basis
• Compare to a specified required period• Decision Rule - Accept the project if it
pays back on a discounted basis withinthe specified time
9-10
Computing Discounted Payback forthe Project
9-11
Advantages and Disadvantages ofDiscounted Payback
• Advantages• Includes time value of
money• Easy to understand
• Disadvantages• May reject positive
NPV investments• Requires an arbitrary
cutoff point• Ignores cash flows
beyond the cutoff point• Biased against long-
term projects, such asR&D and new products
9-12
Average Accounting Return
• There are many different definitions foraverage accounting return
• The one used in the book is:• AAR = Average net income
Average book value• Note that the average book value depends on
how the asset is depreciated.• Need to have a target cutoff rate• Decision Rule: Accept the project if the
AAR is greater than a preset rate.9-13
Computing AAR For The Project
9-14
Advantages and Disadvantagesof AAR
• Advantages• Easy to calculate• Needed information
will usually beavailable
• Disadvantages• Not a true rate of
return; time value ofmoney is ignored
• Uses an arbitrarytarget cutoff rate
• Based on accountingnet income and bookvalues, not cash flowsand market values
9-15
Profitability Index
• Measures the benefit per unit cost, basedon the time value of money
• The PI = PV of the cash inflowsPV of cash outflow
• A profitability index of 1.1 implies that forevery $1 of investment, we create anadditional $0.10 in value
• This measure can be very useful insituations in which we have limited capital
9-16
Advantages and Disadvantagesof Profitability Index
• Advantages• Closely related to NPV,
generally leading toidentical decisions
• Easy to understandand communicate
• May be useful whenavailable investmentfunds are limited
• Disadvantages• May lead to incorrect
decisions incomparisons ofmutually exclusiveinvestments
9-17
Net Present Value
• The difference between the market valueof a project and its cost
• How much value is created fromundertaking an investment?• The first step is to estimate the expected
future cash flows.• The second step is to estimate the required
return for projects of this risk level.• The third step is to find the present value of
the cash flows and subtract the initialinvestment.
9-18
NPV – Decision Rule
• If the NPV is positive, accept theproject• A positive NPV means that the project
is expected to add value to the firm andwill therefore increase the wealth of theowners.
• Since our goal is to increase ownerwealth, NPV is a direct measure ofhow well this project will meet ourgoal.

Computing NPV for the Project
9-21
Internal Rate of Return
• This is the most important alternative toNPV
• It is often used in practice• It is based entirely on the estimated cash
flows and is independent of interest ratesfound elsewhere
9-22
IRR – Definition and DecisionRule
• Definition: IRR is the return that makes theNPV = 0
• Decision Rule: Accept the project if theIRR is greater than the required return
9-23
Computing IRR For The Project
• If you do not have a financial calculator,then this becomes a trial and errorprocess

The NPV Profile
• The NPV Profile shows what the NPV would beat various discount rates.
• For normal projects, the NPV profile is slightlyconvex(slightly curvature toward the origin), butover small intervals, the assumption that it is astraight line is not too bad.
• Since the IRR is the rate that results in an NPVof zero, the IRR is the point on the NPV profilewhere it crosses the horizontal axis.
Congruent Triangles
• One property of congruent triangles is thatthe ratios of their sides is always equal.
• This is the fundamental relationship thatallows us to use trigonometry.
• The triangle will help us to find IRR, wherethe profile crosses the horizontal axis.
• This axis creates a second congruenttriangle.

Conflicts Between NPV and IRR
• NPV directly measures the increase invalue to the firm
• Whenever there is a conflict between NPVand another decision rule, you shouldalways use NPV
You would use the following decision rules:NPV- choose the project with the higherNPVIRR- choose the project with the higherIRR
9-36
Another Example – Non-conventional Cash Flows
• Suppose an investment will cost $90,000initially and will generate the following cashflows:• Year 1: 132,000• Year 2: 100,000• Year 3: -150,000
• The required return is 15%.• Should we accept or reject the project?

Summary of Decision Rules
• The NPV is positive at a required return of15%, so you should Accept
• If you use the financial calculator, youwould get an IRR of 10.11% which wouldtell you to Reject
• You need to recognize that there are non-conventional cash flows and look at theNPV profile
